The Blue Marble is a photograph of Earth taken on December 7, 1972, by either Ron Evans or Harrison Schmitt aboard the Apollo 17 spacecraft on its way to the Moon.Viewed from around 29,400 km (18,300 mi) from Earth's surface, [1] a cropped and rotated version has become one of the most reproduced images in history.
The satellite will fly two radar antennas at either end of a 10 m (33 ft) mast, allowing it to measure the elevation of the surface across a 120 km (75 mi) wide swath. The new radar system is smaller than, but similar to, the one that flew on NASA's Shuttle Radar Topography Mission (SRTM), which made high-resolution measurements of Earth's land ...
Carried the Aquarius instrument, which measured ocean salinity (salt concentration) which improves knowledge of heat transport and storage in the ocean. Mission ended June 2015 due to satellite power supply failure. [38] TOPEX/Poseidon: Inactive NASA and CNES: 1992 Part of NASA's Earth-Sun System Missions. Retired 2006. TRMM: Inactive NASA and ...
Space Force members can be NASA astronauts, with Colonel Michael S. Hopkins, the commander of SpaceX Crew-1, commissioned into the Space Force from the International Space Station on December 18, 2020. [190] [191] [192] In September 2020, the Space Force and NASA signed a memorandum of understanding formally acknowledging the joint role of both ...
They may be astronauts, but first, they're aquanauts. Before they go to the International Space Station, NASA astronauts head the other direction -- to the bottom of the ocean. They dive down to ...
Now that NASA is planning new missions to the Moon with project Artemis, it needs the most detailed maps of our satellite ever produced. To that end, scientists from NASA, the United States ...
Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) is a 2020s NASA Earth-observing satellite mission to observe global ocean color, biogeochemistry, and ecology, as well as the carbon cycle, aerosols and clouds. [3] PACE is intended to be used to identify the extent and duration of phytoplankton blooms and improve understanding of air quality. [4]
The first salinity maps from space were provided by the European Space Agency satellite SMOS (Soil Moisture and Ocean Salinity) that was launched in November 2009. [9] Previous satellites enabled measurement of ocean currents, sea surface temperature and winds, and ocean color. Aquarius adds the ability to measure another ocean variable – the ...
